Abstract

Cancer is a major cause of death, and considerable research has been done to / determine factors for its diagnosis and prognosis. As cancer tumor cells rapidly / reproduce, they use up the available oxygen in an area, creating a condition / known as hypoxia. Normal cells, like immune cells, are unable to tolerate this, but / tumor cells continue to proliferate. Current research indicates that tumor cells are / able to change their metabolism and energy production pathways to cope with / hypoxia. However, research also indicates that stromal cells interact closely with / tumor cells, with potentially significant consequences that may affect their / survival. My project shows that under hypoxia, tumor cells survive better when / cocultured with their associated fibroblasts than when cultured alone. Fibroblasts, / on the other hand, did not undergo noticeable change. This suggests that / interactions between the cells significantly affected the tumor cells' ability to / withstand hypoxia. Future research will identify this interaction, and ultimately / eliminate it to make tumor cells more sensitive to treatments.
